China is the place of origin of the azalea, which was later introduced to Europe by European countries and crossbred with local varieties to obtain the excellent horticultural variety "four-season azalea", distributed in the Netherlands, Belgium, Denmark, Germany, etc. Because Belgium has the most varieties, they are also collectively called Belgian azaleas. It likes cool conditions and dislikes high heat; it dislikes strong sunlight and likes semi-shade; its roots are fine and shallow, fearing both drought and waterlogging; it dislikes strong fertilizer, which easily damages the roots; it likes weakly acidic soil and water and dislikes salinity and alkalinity; the optimum growth temperature is 20-25°C.

China is the place of origin of the azalea, which was later introduced to Europe by European countries and crossbred with local varieties to obtain the excellent horticultural variety "four-season azalea", distributed in the Netherlands, Belgium, Denmark, Germany, etc. Because Belgium has the most varieties, they are also collectively called Belgian azaleas.

It likes cool conditions and dislikes high heat; it dislikes strong sunlight and likes semi-shade; its roots are fine and shallow, fearing both drought and waterlogging; it dislikes strong fertilizer, which easily damages the roots; it likes weakly acidic soil and water and dislikes salinity and alkalinity; the optimum growth temperature is 20-25°C.

The northern climate is cold in winter and hot and dry in summer, and the soil and water tend to be alkaline, making it very unsuitable for azalea growth. When cultivating azaleas in the north, conditions suitable for azalea growth must be created.

The following points should be noted:

1. In spring and summer, pay attention to shading and moisture retention. Belgian azaleas like a semi-shady, well-ventilated, humid environment. Water should often be sprinkled on the ground and surroundings to maintain humidity, and 50-70% shade netting should be used for shading.

2. In autumn, pay attention to pruning the plant. Belgian azaleas can form flower buds in all four seasons. If you want them to bloom before the Spring Festival, the azaleas should be pruned in July-August, so that the flower buds formed can bloom before the Spring Festival.

3. In winter, pay attention to keeping warm. When the temperature is below 10°C, Belgian azaleas are almost in a state of stopped growth, so the greenhouse temperature should be kept above 10°C.

4. Watering and fertilizing should be done with the right amount of fertilizer. Belgian azalea roots are fine and shallow, fearing both drought and waterlogging. If too dry, the leaf tips will scorch; if too waterlogged, the leaves turn yellow and the central leaves curl. When watering, 1‰ ferrous sulfate can be added, and the fertilizer concentration must not exceed 2‰.

As long as the methods are appropriate, Belgian azaleas can also be grown in the north in a blaze of bloom.
